JSVM

Overview

This module provides standard JavaScript (JS) engine capabilities. The standard JS engine is a JS code execution engine that strictly complies with the ECMAScript. It supports the standard libraries defined by ECMAScript and provides complete native APIs to implement interaction between C++ and JS modules. Just-In-Time (JIT) compiler is used to accelerate code execution and provide secure and efficient JS execution capabilities for applications. The capabilities of the standard JS engine are provided through a stable set of application binary interfaces (ABIs), that is, JSVM-APIs. They can be dynamically linked to JS engine libraries of different versions to shield the differences between engine interfaces. JSVM-APIs provide capabilities such as engine lifecycle management, JS context management, JS code execution, JS/C++ interoperability, execution environment snapshot, and code cache.
Platform: ARM64.
Usage: Link libjsvm.so in the SDK and include the ark_runtime/jsvm.h file in the C++ code.
